Local storm reports filed while the alert was in force, from inside its polygon or its counties.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Brookhaven, NY (KOKX), launched 12:00Z, 11.1 hours before the alert went out and 18 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE UPTON NY
403 PM EDT FRI JUL 6 2007
.SYNOPSIS...
AFTER AN UPPER LEVEL DISTURBANCE MOVES EAST THIS EVENING...HIGH
PRESSURE AT THE SURFACE WILL BUILD OVER THE AREA FROM THE OHIO
VALLEY INTO SATURDAY. HIGH PRESSURE OVER THE WESTERN ATLANTIC WILL
THEN STRENGTHEN AND ALSO BRING HOT AND HUMID WEATHER INTO THE AREA
FOR SUNDAY AND MONDAY. LOW PRESSURE AND AN ASSOCIATED COLD FRONT
WILL MOVE INTO THE NORTHEAST AND STALL NEARBY FOR THE MIDDLE OF NEXT
ANOTHER COLD FRONT WILL PASS THROUGH THURSDAY NIGHT INTO
FRIDAY...FOLLOWED BY HIGH PRESSURE BUILDING BACK IN.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
LATEST WATER VAPOR LOOP SHOWING A MID-UPPER LEVEL SHORTWAVE IN THE
VICINITY OF KALB...MOVING JUST ABOUT DUE EAST. THIS HAS BEEN
HELPING TO TRIGGER SHOWERS AND THUNDERSTORMS TO OUR NORTH...AND WITH
MLCAPES AROUND 1000 J/KG LASTING INTO THE EARLY EVENING...WILL KEEP
MENTION OF SHOWERS AND THUNDERSTORMS FOR THE EVENING. WITH THE
SHORTWAVE AXIS TO OUR EAST...AND CAPES GENERALLY HIGHER ACROSS THE
NORTHERN ZONES...HIGHEST POPS WILL BE ACROSS CT.
WEAK HIGH PRESSURE BEGINS TO BUILD IN LATE TONIGHT WITH
DRYING/CLEARING CONDITIONS. LOWS RANGING FROM THE UPPER 60S TO
AROUND 70 IN THE CITY...AND INTO THE UPPER 50S FOR THE NORTHERN TIER
OF THE CWA.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/...
THE COLD POOL ALOFT CONTINUES TO HEAD EAST ON SATURDAY...WITH
RIDGING IN THE MID AND UPPER LEVELS. WEAK HIGH PRESSURE AT THE
SURFACE WILL CONTINUE TO BUILD IN FROM THE WEST WHILE A WARM FRONT
SPREADS ACROSS NORTHERN NEW YORK. MOSTLY SUNNY WITH MODERATING
TEMPERATURES. H8 TEMPERATURES WILL CLIMB TO AROUND 14C IN THE
AFTERNOON. THIS...COMBINED WITH PLENTY OF SUN AND DECENT
DOWNSLOPING SHOULD TRANSLATE TO HIGHS GENERALLY IN THE MIDDLE TO
UPPER 80S. FWC MOS LOOKS A LITTLE TOO WARM...SO USED A MET/MAV MOS
BLEND FOR HIGHS.
HIGH PRESSURE TO OUR SOUTH WILL MOVE OFFSHORE ON SUNDAY. WINDS WILL
BE FROM THE WSW...AND LOW LEVEL TEMPERATURES AND MOISTURE WILL BEGIN
TO INCREASE. ONCE AGAIN...FWC MOS LOOKS A LITTLE TOO WARM FOR HIGHS
GIVEN FORECAST H8 TEMPS AROUND 18C. A MET/MAV MOS BLEND WAS USED
AGAIN FOR HIGHS...WITH THE WARMEST LOCALES REACHING THE MID 90S. H8
DEW POINTS DURING THE AFTERNOON ONLY EXPECTED TO BE AROUND 10C TO
11C...SO RELATIVELY DRIER AIR IS EXPECTED TO MIX DOWN FROM ALOFT.
KNOCKING A DEGREE OR TWO FROM MAV MOS GUIDANCE (WHICH WAS THE
LOWEST) PRODUCES DEW POINT TEMPERATURES AT OR SLIGHTLY ABOVE 60
DURING THE AFTERNOON. HEAT INDICES THEREFORE TOPPING OUT IN THE MID
TO UPPER 90S FOR THE WARMEST SPOTS.
H5 HEIGHTS BUILD SUNDAY NIGHT...THEN THE UPPER FLOW BECOMES ZONAL ON
MONDAY. SURFACE LOW IN SOUTHEASTERN CANADA WILL WEAKEN...BUT WILL
STILL MANAGE TO DRAG A COLD FRONT INTO THE NORTHEAST. FOR NOW IT
LOOKS LIKE THE MORNING HOURS SHOULD REMAIN DRY...BUT THE FRONT MAY
BE CLOSE ENOUGH IN THE AFTERNOON TO WARRANT A CHANCE OF SHOWERS AND
THUNDERSTORMS BY DAYS END. THIS MAY ALSO HAVE IMPLICATIONS ON HIGHS
FOR MONDAY AS WE MAY NOT GET FULL SUN POTENTIAL TEMPERATURES. H8
TEMPS ARE FORECAST TO RISE TO AROUND 19C TO 20C. EVEN WITHOUT THE
HELP OF A DOWNSLOPE FLOW...LOW TO MID 90S COULD BE ACHIEVED.
THINKING IS THAT THERE WILL BE ENOUGH SUN AND DOWNSLOPE TO GO WITH
HIGHS IN THE MID TO UPPER 90S FOR THE NORMALLY WARMEST SPOTS. H8 DEW
POINTS ARE EXPECTED TO INCREASE TO AROUND 14C. SURFACE DEW POINTS
THEREFORE EXPECTED GENERALLY IN THE LOW TO MID 60S DURING THE
AFTERNOON. HEAT INDICES WILL BE CLOSE TO HEAT ADVISORY CRITERIA OF
100 IN THE NYC METRO AREA...AND IS FORECAST TO REMAIN BELOW 105
ELSEWHERE ATTM. WILL CONTINUE TO HIGHLIGHT THIS IN THE HWO.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
H5 FLOW WILL BE NEARLY ZONAL OVER THE NORTHEAST THROUGH WEDNESDAY.
SURFACE LOW MOVING THROUGH QUEBEC WILL CONTINUE TO MOVE GENERALLY
EAST...SLOWLY DRAGGING A COLD FRONT THROUGH NEW YORK STATE MONDAY
NIGHT. THE FRONT WILL PASS THROUGH THE TRI STATE AREA ON TUESDAY
BEFORE STALLING JUST TO THE SOUTH ON WEDNESDAY. WITH THE COLD FRONT
NEARBY DURING THIS PERIOD...THERE WILL BE A CHANCE OF SHOWERS AND
THUNDERSTORMS. HIGH TEMPERATURES ON TUESDAY AND WEDNESDAY WILL
LARGELY DEPEND ON THE ULTIMATE TIMING AND LOCATION OF THE COLD
FRONT. HPC GUIDANCE WAS FOLLOWED...WHICH YIELDED NEAR NORMAL
TEMPERATURES.
THE H5 FLOW BEGINS TO AMPLIFY ON THURSDAY WITH A TROUGHING IN THE
REGION THROUGH FRIDAY. AN ASSOCIATED SURFACE LOW WILL MOVE ACROSS
THE HUDSON BAY VICINITY. THIS WILL PUSH THE STALLED FRONTAL BOUNDARY
TO OUR SOUTH...RESULTING IN A WARM FRONT PASSAGE THURSDAY MORNING. A
TRAILING COLD FRONT THEN MOVES THROUGH SOMETIME THURSDAY NIGHT OR
EARLY FRIDAY MORNING WITH MORE SHOWERS AND STORMS POSSIBLE. HIGH
PRESSURE BUILDING IN BEHIND IT THROUGHOUT FRIDAY WITH DRYING
CONDITIONS.
&&
.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
UPPER LEVEL DISTURBANCE MOVING ACROSS UPSTATE NY...AND WILL SLIDE
EAST THROUGH THE REMAINDER OF THE AFTERNOON. SCATTERED SHRA/TSTMS
DEVELOPING IN UNSTABLE AIRMASS TO THE NORTH. COULD SEE SOME OF
THIS ACTIVITY FOR A FEW HOURS...WITH BEST CHANCE AT KSWF.
OTHERWISE...VFR CIGS/VSBYS WITH GENERAL NORTHWEST WIND FLOW THIS
AFTERNOON. LOW LEVEL LAPSE RATES CONDUCIVE FOR MIXING...BUT FEEL
16 TO 18 KTS HIGHEST GUSTS WE WILL SEE THIS AFTERNOON.
LOCAL SEA BREEZES WILL BATTLE NW SYNOPTIC SCALE FLOW...AND SEA
BREEZE SHOULD BE KEPT TO A MINIMUM AT KBDR/KISP/KGON AND KJFK.
THEN AS THE SHORTWAVE/SFC FRONT MOVES TO THE EAST THIS EVENING...LIGHT
NW FLOW AND CLEARING OCCUR OVERNIGHT. ANY AFTERNOON CONVECTION
WILL SUBSIDE RATHER QUICKLY THIS EVENING AS UPPER SUPPORT EXITS
AND DIURNAL HEATING ENDS. NOT TOO SURE IF ANY MVFR FOG DEVELOPS
OUTSIDE METRO AIRPORTS IN WEAK NW FLOW. SLIGHTLY DRIER AIR SHOULD
KEEP FOG TO A MINIMUM.
NW TO W FLOW FOR SATURDAY MORNING WITH ONLY SOME MID CLOUDS EXPECTED.
OUTLOOK FROM 18Z SATURDAY THROUGH TUESDAY...VFR CIGS/VSBYS EXPECTED
THROUGH MONDAY AFTERNOON AS HIGH PRES BUILDS INTO THE NORTHEAST. A
COLD FRONT WILL TRY TO PUSH THROUGH MONDAY NIGHT INTO EARLY
TUESDAY AND MAY SPARK CONVECTION. THIS FRONT COULD GET HUNG UP IN
OUR VICINITY THROUGH TUESDAY AS UPPER STEERING FLOW BECOMES PARALLEL
TO SFC FRONT.
&&
.MARINE...
COLD FRONT SLOWING MOVING ACROSS THE AREA WATERS WILL PUSH SOUTH
THIS EVENING. THERE WILL BE A CHANCE OF WIDELY SCATTERED SHOWERS AND
TSTMS THROUGH THIS EVENING.
WINDS ARE MAINLY OUT OF THE WEST/SOUTHWEST ACROSS THE WATERS. THIS
WILL ALLOW FOR SEAS TO SLOWLY SUBSIDE THROUGH THIS AFTERNOON AND
INTO TONIGHT. HAVE DROPPED SCA FOR CENTRAL OCEAN ZONES
(ANZ353)...BUT WILL LET IT CONTINUE JUST TO THE EAST THROUGH AT
LEAST MIDNIGHT AS OBSERVATIONS OF 6 TO 7 FT REMAIN. AS WINDS SUBSIDE
AND SHIFT MORE TOWARDS THE WEST...SEAS WILL GRADUALLY SUBSIDE AFTER
MIDNIGHT.
AN AREA OF HIGH PRESSURE WILL THEN BUILD OVER THE WATERS TONIGHT
INTO SUNDAY. THE HIGH WILL THEN MOVE SOUTH...ALLOWING A COLD FRONT
TO APPROACH. THE FRONT WILL LIKELY STALL NORTH OF THE WATERS AND
SHIFT BACK NORTH LATE MONDAY INTO TUESDAY. THERE WILL AGAIN BE A
CHANCE OF SHOWERS AND THUNDERSTORMS MONDAY AND TUESDAY OVER THE
WATERS.
A SOUTHERLY FLOW AHEAD OF THE COLD FRONT WILL BUILD SEAS ON THE
OCEAN BACK UP TO SMALL CRAFT LEVELS ON THE OCEAN. SEAS WILL LIKELY
REMAIN ABOUT SMALL CRAFT LEVELS INTO TUESDAY...THEN SUBSIDE BY
WEDNESDAY.
&&
.HYDROLOGY...
AFTERNOON SHOULD PRODUCE GENERALLY AREAL QPF LESS THAN 1/4
INCH...AND SOME LOCALIZED TOTALS OF 1/2 TO 3/4 INCH ESPECIALLY OVER
INTERIOR SOUTHERN CT.
MAINLY DRY CONDITIONS ARE EXPECTED TONIGHT INTO MONDAY
MORNING...BUT THEN THERE IS SOME UNCERTAINTY FROM TUE AND BEYOND
AS TO THE EXACT POSITION OF A COLD FRONT EXPECTED TO DROP S FROM THE
UPPER GREAT LAKES. IF THE FRONT STALLS NEARBY...THERE WOULD BE A
GREATER POTENTIAL FOR AFTERNOON/EVENING CONVECTION THAT COULD CAUSE
URBAN/POOR DRAINAGE/SMALL STREAM FLOODING.
